Authorities in Indonesia have now located the black boxes from the Boeing 737 airliner that crashed into the sea on Saturday, and hope the devices will provide some answers.
There has been no clues yet to what brought down the Sriwijaya Air passenger jet, with 62 people aboard, and search and rescue efforts are ongoing.
Some victims' remains have been found.
For relatives of those aboard, heartbreak. Family members are providing DNA samples to help identify their loved ones.
Rafiq Yusuf Al Idrus had his wife on the plane.
"The last time she contacted me was 2:05 p.m. She was still laughing on WhatsApp, saying that she'd already boarded the plane and was told the weather condition isn't good. Then I said 'Yes, pray a lot, please.'"
It was raining when the plane took off shortly after 2:30 for a short trip to a neighboring island.
The plane was a 27-year old 737-500 model, which is much older than Boeing's controversial 737-MAX, although it's widely flown and doesn't share the same equipment implicated in the MAX's safety crisis.
Sriwijaya Air also has a solid safety record.
However, Indonesia has a troubled history with air safety. In 2007 the European Union banned all Indonesian airlines after a series of crashes and other safety problems in the 1990s.
The ban wasn't fully lifted until 2018. That was the same year of the Lion Air disaster, in which a 737-MAX operated by a different Indonesian airline plunged into the sea, killing everyone aboard.
